铁路客运专线无碴轨道隧道渗漏水的预防与整治

首先介绍了隧道衬砌、底板等不同部位出水对隧道产生的不同危害,然后分析了由于防水板技术指标标准较低、防水材料选用不当、缺乏针对性的加强设计、施工质量不能保证等造成隧道渗漏水的原因,提出应做好施工过程控制、确保开挖轮廓圆顺、及时优化隧道设计等相应预防工作,对衬砌边墙、施工缝和仰拱顶面渗水均阐述了整治措施,并指出隧道底部渗漏水是治理的重点。

The Prevention and Treatment of the Water Leakage in the Ballastless Track Tunnels of the Passengers-oriented Railway

The various kinds of damage that water leakage at different sections such as the lined parts,bottom plates, etc. , may do to the tunnel is first introduced in the paper, with the causes for the water leakage analyzed, such as the low standards for waterproof boards, improper selection of waterproof materials, the lack of the specific strengthening design, the poor quality of construction etc. , upon the basis of which it is strongly suggested that a good job should be done of controlling the construction process, the excavation of a smoother profile should be ensured, the tunnel design should be timely optimized, etc. Treating measures for the lining, sidewalls, construction joints, and water seapage at the down part of the tunnel top surface are also presented, with the importance of treating the water leakage at the bottom of the tunnel pointed out and stressed.
